That bisection, focussing on wpa_supplicant running versus ESSID:off/any (indeed they match up), now completed on the Aspire One (I'll assume for the moment that the laptop would show the same). Yes, it does appear that the patch I originally pointed to introduced a problem which later got fixed, but was enough to throw the bisection off when I just looked for "wireless not working". But you can't escape, you've been too busy, the guilty patch is... a9a11622c5c742c115fad371c0397ae86dd3bb67 is first bad commit commit a9a11622c5c742c115fad371c0397ae86dd3bb67 Author: Johannes Berg Date: Mon Jul 27 12:01:53 2009 +0200 cfg80211: self-contained wext handling where possible Finally! This is what you've all been waiting for! This patch makes cfg80211 take care of wext emulation _completely_ by itself, drivers that don't need things cfg80211 doesn't do yet don't even need to be aware of wireless extensions. This means we can also clean up mac80211's and iwm's Kconfig and make it possible to build them w/o wext now! RIP wext. Signed-off-by: Johannes Berg Signed-off-by: John W.
